Respiratory Care Program Could Decrease Pulmonary Complications in Surgical Patients

October 4, 2012

Respiratory complications—including pneumonia and ventilator dependency—are among the most common complications that occur after operations. But a simple and inexpensive postoperative pulmonary care program known as “I COUGH”(SM) reduces the likelihood of those life-threatening and costly complications, researchers from Boston University Medical Center reported today at the 2012 American College of Surgeons (ACS) Annual Clinical Congress.

“Few data exist for best-practice guidelines regarding postoperative pulmonary care,” explains study coauthor David McAneny, MD, FACS, associate professor of surgery, Boston University School of Medicine. “There is a lot of medical literature about ventilator-associated pneumonias, but little is written about standard postoperative pulmonary care.”

Boston University Medical Center participates in the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP®). ACS NSQIP is the leading nationally validated, risk-adjusted, outcomes-based program to measure and improve the quality of surgical care in private sector hospitals. Benchmark reports from this national database allow hospitals to compare their surgical outcomes and other factors to comparable patients in the other institutions participating in the program.

“The NSQIP data showed that our hospital had a greater than expected incidence of pulmonary complications, as well as venous thromboembolic complications, based upon our patients’ risk factors. So we developed the I COUGH program to decrease the incidence of pulmonary complications,” McAneny says.

I COUGH stands for: • Incentive spirometry• Coughing/deep breathing• Oral care • Understanding (patient and staff education)• Getting out of bed at least three times daily• Head of bed elevation.

“Our efforts were aimed at correcting basic nursing interventions as well as intensified patient and family education before the operation and in the immediate postoperative period,” McAneny adds.

For the study, researchers compared their risk-adjusted pulmonary outcomes, which NSQIP initially reported as observed-to-expected ratios (O/E), from the one-year period prior to implementing I COUGH, with the odds ratios (OR; statistically comparable to O/E) for the one-year period following the program’s implementation. The findings showed that the intervention reduced the likelihood of pneumonia after surgery (2.13 O/E versus 1.58 OR, respectively) and of unplanned intubation (2.10 O/E versus 1.31 OR, respectively) at their institution.

At the same time, study results revealed another favorable outcome: a decline in venous thromboembolic (VTE) complications (3.41 O/E versus 1.35 OR, respectively). “By virtue of the fact that there was a greater focus on mobilizing patients out of bed soon after their operations and on standardizing their pulmonary care, in addition to an early program of risk-stratified prophylaxis against VTE complications, we concommitantly saw a dramatic decrease in venous thromboembolic complications,” McAneny says. “We are excited about these results.”

In August 2010, the I COUGH initiative was implemented by the hospital’s multidisciplinary team composed of surgeons, surgical residents, internal medicine physicians, nurses, quality improvement and infection control experts, respiratory therapists, and physical therapists. “Because the program is hard wired into the computerized physician orders, the I COUGH program steps are automatically ordered on all patients,” McAneny says.

Ultimately, the research team aims to improve respiratory care and reduce costs by achieving a standardized level of care throughout their entire institution. The program’s goal is to decrease the number of postoperative respiratory complications hospital wide by at least 50 percent, according to McAneny.

“We have two campuses and are standardizing the care between the campuses,” he said. “The costs of these serious complications can range from $18,000 to $52,000 per event, and we estimate at least $1 million in savings at our institition from these interventions,” McAneny says.
